yes, initially leveling on a PVP server is more difficult then leveling on a PVE server,
but after you hit 80 (and have a flying mount) it becomes quite a minor thing.
The majority of us on Mannoroth are PVE focused now,
hasn't been a lot of progress in the PVP department from Blizz in a long time.
We have had a few people come over from PVE recently and the way Blizzard has things are set up now,
its easier then ever to level. And a great deal of the Dailies, including the Tournament area are nonattack zones.
Also we are fairly supportive and tend to help bring the pain
Almost all of us have multiple 80's and help folks level
